Benefits of technology

The patent text describes a method of using water cooling to improve the performance and lifespan of solar PV panels. This is achieved by creating a layer of water on the panels, which reduces the temperature and prevents dust accumulation. The water layer also collects additional sunlight and improves the electrical performance of the panels. This results in improved performance and reduced maintenance costs. The cooling system is designed as an open loop system, which eliminates the need for electrical power and increases the efficiency of the solar power facility. Additionally, the use of a ram pump eliminates concerns related to energy consumption and pumping time.

Problems solved by technology

In addition, the water cooling reduces thermal cycling which results in extending the lifetime of the solar PV panels.

Abstract

A solar photovoltaic panel system which has a thermal sink and a panel mounting structure is provided. The panel mounting structure contains a water flow section. The water flow section includes an inflow section and an outflow section. A solar photovoltaic panel is mounted between the inflow section and the outflow section. A water supply system is connected to the panel mounting structure to provide water on a top surface of the solar photovoltaic panel. The water provided from the thermal sink is returned to the thermal sink after flowing on the top surface of the solar photovoltaic panel.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention relates to cooling solar photovoltaic (PV) panels (cool solar), and in particular to systems and methods for water-cooling solar PV panels based on a water supply system which includes a ram pump, and which provides water from a water thermal sink for treating solar PV panels with water to cool, clean and increase the efficiency of the solar PV panel system.[0003]2. Description of Related Art[0004]Solar photovoltaic systems, which rely on sunlight striking panels of photovoltaic elements to produce electricity, have been known for some time.[0005]The use of such solar photovoltaic panels has been known to involve several problems. One problem relates to applied solar energy resulting in heating the photovoltaic panel to an increased temperature, which results in a decrease in the photoelectric conversion efficiency. Another problem has been the deposition of particulate matter (e.g., dust, debris, etc.) o...
